REFRIGERATOR-CAR.

SPECIFICATION forming part of Letters Patent No. 577,748, dated February23, 1897.

Application led May 6, 1896. Serial No. 590,440.- (No model.)

To all whom, t may concern:

Be it known that I, CHARLES S. HARDY, of San Diego, in the county of SanDiego and State of California, have invented a new and usefulImprovement in Refrigerator-Cars, of which the following is aspecification.

^ My invention is an improvement in refrigerator-cars, and particularlyin that class of such cars having folding ice-receptacles; and thepresent invention has for objects, among others, to provide improvementsin the packing of the folding parts of the ice-receptacle and in thespatter devices of the drain-flue; and the invention consists in certainnovel constructions, combinations, and arrangements of parts, as will behereinafter described, and pointed out in the claims.

In the drawings, Figure l is a vertical longitudinal section of a carprovided with my improvements,partsbeingbrokenaway. Fig. 2 is across-section on about line 2 2 of Fig. l. Fig. 3 is a detail enlargedsection of the drainflue; and Fig, I illustrates a modified arrangementof the improved spatter devices.

The ice-receptacle A has the hinged bot-tom or iioor section B and thehinged side section C, the section B connecting with thedrainiiue D andthe section C with the draft-flue E. The part A is an ice-receptacle,and the floor and side sections are hinged so they can be adjusted toform the ice-receptacle, when desired, or be folded up out of the way.The

drain-flue has its inner wall D provided at its upper end with apacking-strip d, of rubber or other suitable flexible material, whichstrip extends from side to side of the drainflue and forms a packingbetween the floorsection B of the ice-receptacle and the drainiiue, sosuch parts will be sealed at their meeting point or juncture by theweight of the floor B and by internal pressure received from ice when inuse as a refrigerator. A packing-strip f, of rubber or the like, isarranged to seal the joint between the floor B and the wall C.

At the juncture of the ice-receptacle with the draft-iue F.,I provide apacking-strip e, of rubber or other suitable flexible material, suchstrip being supported in and extended from side to side of the ceilingformingsuchv draft-flue. This packing serves to seal the joint betweensuch draft-flue and the wallsection C of the ice-receptacle and is aidedby internal pressure received from ice when used as a refrigerator.

In forming the drain-flue of an ice-receptacle it is desirable toconcentrate the flue into the smallest possible space, gain as muchspace as possible for the passage of air, and to so arrange spatterdevices that the drippings from ice in the receptacle will not falldirectly to the iioor and spatter out into the car, and that suchdevices will offer the greatest freedom to the passage of the air.

In the present arrangement of spatter devices I provide the sidesections or deflectors F and the intermediate deflector or section G.The deflectors F project alternately from the opposite sides of theflue, but terminate atthere is nothing but declining surfaces toobstruct the passage of air.

In Fig. 4 I show a somewhat-modified arrangement of the side andintermediate deectors which may be used in some instances, butordinarily Iprefer the construction shown in Fig. 3.

By means of the packing-strips d and e, the strips 7i on the cleats I-I,as best shown in Fig. 2, each part of the folding ice-receptacle willrest upon packing material at all its outer edges and become sealed byits own weight and the interior pressure received from ice when in useas a refrigerator.

It will be understood that the side section C is sealed against itscleats in substantially the same manner as the bottom B is sealed at b,as shown in Fig. 2.

It should be understood that to obtain perfect results fromrefrigeration it is necessary to have the ice-receptacle not onlyair-tight, but water-tight as well, at all points except where openingsare left, except the inlet and discharge.

Having thus described my invention, what 2. The combination of theice-receptacle having 'a hinged floor-section, a drain-flue arranged atits upper end to be abntted by said Section and a. sealing-strip sealingthe joint 15 between said parts substantially as shown and described.
